SPECIFICATION forming part Of Letters Patent N0. 632,835, datedSeptember 12, 1899.

Application filed March 10, 1898. Serial No. 673,290. (No model.)

- Montour Falls, in the county ofSchuyler, in

the State of New York, have invented new and useful Improvements inPliers, of which the following,taken in connection with the accompanyingdrawings, is a full, clear, and exact description.

My invention relates to improvements in combination pliers andstaple-pullers; and the object is to provide a simple and efficientdevice and at the same time construct the same in such a manner that itmay be easily repaired should the jaws of the staple-pulling devicebecome broken.

In the drawings hereto annexed and forming a part of this specification,Figure 1 is a perspective View of my invention. Fig. 2 is a side view ofthe pliers engaged with a staple and in a position to withdraw thestaple from a wall. Fig. 3 is an end view showing the jaws closed. Fig.4 is an enlarged detached view of one of the jaws of the staple-pullingmeans. Fig. 5 is an end view of one of the members of the pliers havinga staple-pulling jaw riveted therein. Fig. 6 shows a portion of one ofthe members of the pliers having a staple-pulling jaw secured thereto bya screw; and Fig. 7 is an end view of the same.

It will be apparent that my invention consists in providing pliershaving either flat or round noses or pliers of any description oranalogous instruments with removable staplepulling devices or jaws, sothat if said jaws are broken or injured they may be easily removed andothers inserted. Heretofore the staple-pulling jaws were integral withthe members of the pliers, and if the said jaws were broken the tool wasworthless for the purpose of pulling staples, necessitating the purchaseof another. With my improved tool it is only necessary to be providedwith a few of these jaws, and when one is accidentally broken it may beeasily removed and a new one inserted with very little expense.

My invention, it will be seen, is combined with a device which includesseveral toolsnamely, flat pliers, hammer, and wire-cutter. In fact,there are shown in the device in the drawings a pair of hammer-faces,one on each jaw of the pliers, and a pair of shear wire-cut ters onopposite sides of the bolt or rivet. The wire-cutters are in themselvesold and well known and need not be described herein in detail.

Referring specifically to the drawings, A A indicate theplier-jaws,which are fiat and preferably roughened on theirclamping-surfaces and tapered on their outer surfaces, as usual in flatpliers. Each jaw is provided with a fiat hammer-face B B, which allowsthe pliers to be used as a hammer whichever side is uppermost withoutchanging its position in the hand.

G C are the wire-cutters,located on each side of the bol tor rivet D, bywhich the pliers A A, with their handles A A, are secured together. Saidcutters are each formed by a pair of recesses in the edges of the partswhich coincide with each other when the jaws are open, and pass eachother while closing the jaws in the usual and well-known manner.

Each jaw and handle are made in one piece, the portion of the handlewhere it is pivoted to the other handle being recessed and interlockedwith the opposite handle, the handles being crossed at theirinterlocking points. The cutters may be of the same size or of differentsizes, and the pliers may be roundnosed pliers or otherwise shapedwithout departing from my invention.

On the flat outer sides of the pliers, between the rivet D and the endsof the noses, are ribs or projections b b, which extend outward at rightangles to the clamping-surfaces of the pliers and open and close withthe pliers when operated. The clamping or gripping ends of theseprojections are inclined or concaved for the purpose of gripping astaple without cutting it. The projections 19 b are preferablyclaw-shaped and flattened on their sides to be engaged by a wrench orother pliers when inserted or removed. Each projection 19 is preferablyprovided with a shank which is either screw-threaded or plain forextending into or through the member of the pliers and securing theparts together. Holes are drilled transversely through the members ofthe p1iers,and these are threaded when the shanks of the staple-pullingjaws are threaded, as

shown in Fig. 4 of the drawings. If these jaws are only applied to oneside of thepliers, the shanks of the jaws may extend entirely throughthe members; but if applied to both sides, as indicated in Figs. 2 and3, they only extend half-way through, two shanks occupying the samehole.

Fig. 5 shows a staple-pulling projection I), having a plain shank 0extending from a shoulder and entirely through the member of the pliers,its end being riveted upon the opposite side. This form is cheaper thanthe threaded form, but is not so easily removed and inserted. When thisform is applied to opposite sides of the member, a pair of holes isnecessary.

Figs. 6 and 7 show different views of a modification wherein thesecuring means for the projection is not integral therewith, but formedof a separate rivet or screw e, which enters or extends through themember of the pliers and also through the projection or jaw 1) 0f thestaple-puller.

In Fig. 2, F is a wall, and E is a staple fixed therein and engaged bymy improved pliers. Bypulling the handles A away from the wall F thestaple will be withdrawn as the ends of the noses of the pliers form afulcrum, resting as they do upon the wall above the staple.

I do not desire to be limited tothe form of 30 pliers or staple-pullin gjaws shown, nor to the securing means for said jaws, as it will beobvious that these may all be widely varied without departing from myinvention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

In a tool, the combination of apair of jaws hinged together, eachprovided with a suitable handle, and a pair of claw-shaped jawsprojecting from the sides of the first-mentioned jaws, and provided withscrew-threaded shanks extending into threaded apertures in the sides ofthe first-mentioned jaws, substantially as described and shown.

In testimony whereof I have hereunto signed my name.

WILLIAM ORONK.
